I, Antonio Ancona, do hereby certify that the 8"x16" Flood Vents by Cooke & Associates, the 8"x16" Solid Door Face and Perforated Door Face with Styro Backing are in compliance with Section 2.6.1.2, SEI/ASCE 24-98, Flood Resistant Design and Construction Standard. This standard requires flood vents to open and prevent unbalanced water elevation to be limited to 12" for the expected maximum flood rate of rise and fall.

The subject flood vents, when open, will provide 98 square inches of opening. Each flood vent will provide 238 sq.ft. of flood protection for a maximum rate of rise and fall of 5 ft/hr. Further it is noted that the use of the vents is subject to the following limitations:

1. The bottom of the vent shall be no higher than 12" from finish grade.
2. There shall be appropriate number of vents per foundation as needed to supply
    1 square inch of net free space for 2.424 square feet of enclosed space for
    maximum rate of rise and fall of 5 ft/hr. The flood protection area per inch
    of opening can be increased, per engineering calculation, for rate of rise and
    fall less than 5 ft/hr, and the flood area per inch of opening shall be reduced,
    per engineering calculations, if the rate of rise and fall is greater than 5 ft/hr.
3. The flood gates shall not be used for crawl space ventilation.
4. And, the vents shall not be restricted as to the operation of the drop out panel,
    this panel must be able to drop out freely at all times. A vent visual inspection
    is recommended after the initial installation and completion of all construction
    work around the vents to ensure that the vent panel is free to drop out.

Sincerely,
